  1. 1. Analys av föda för vitryggig hackspett och rödlistade vedlevande skalbaggar : utvärdering av tre olika behandlingar

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Emma Mattsson; Lena Ostermann; [2023]
    Nyckelord :Vitryggig hackspett; vedlevande skalbaggar; paraplyart; rödlista; biologisk mångfald; död ved; restaurering;

    Sammanfattning : Den vitryggiga hackspetten har sedan 1950-talet blivit en sällsynt art i det svenska landskapet. Nedgången beror främst på det moderna skogsbruket där barrskog till stor del har ersatt blandbestånd och gammal lövskog. LÄS MER

  3. 2. The diversity of fungi in coniferous forests and mixed forests

    Master-uppsats, Karlstads universitet

    Författare :Ida Asplund; [2023]
    Nyckelord :Forest type; coniferous forest; mixed forest; fungi; fungal diversity; mycorrhiza; saprotrothic fungi; parasites; parasitic fungi; Skogstyp; barrskog; blandskog; svampar; svampdiversitet; svampmångfald; mykorrhiza; saprotrofiska svampar; parasiter; parasitiska svampar;

    Sammanfattning : The fungal domain has one of the highest biodiversities among eukaryotes and species within the domain fill important ecological roles, such as mutualistic mycorrhiza, decomposers, parasites and pathogens. The development of forest ecosystems and their related processes has not only been linked to fungal diversity but the composition and abundance of fungi benefits the abundance and diversity of other species as well.

  4. 3. The ability to create mixed stands by planting Norway spruce and Scots pine every second row

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Eva Higgins Andersson; [2022]
    Nyckelord :Local site index; seedlings every second row; regeneration; biodiversity; climate change; establishment;

    Sammanfattning : Swedish forests primarily consist of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.). LÄS MER

  5. 4. Natural oak regeneration in response to selective cutting : restoration of temperate deciduous woodlands on abandoned agricultural land in Scandinavia

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Samuel Keith; [2020]
    Nyckelord :Light demanding species; selective cutting; restoration; ecosystem services; broadleaf dominated;

    Sammanfattning : The natural regeneration of sessile oak (Quercus petraea (Matt.) L.) and pedunculate oak (Quercus robur L.) is largely uncertain across central Europe and Scandinavia. LÄS MER

  7. 5. External timber quality of birch in birch-spruce mixtures

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Fredrik Hörnsten; [2018]
    Nyckelord :mixed-species forestry; birch-spruce mixtures; external timber quality; birch;

    Sammanfattning : The Swedish forest management model, largely based on monocultures of conifer species, has increasingly come under scrutiny. Its disadvantages to biodiversity, recreation and climate change susceptibility incentivize alternative ways of forest production. Mixtures with a secondary species is one such alternative. LÄS MER
